When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
Solve -8a + 5a = -4a + 6y - 5 for a in terms of y.
| -4\(\frac{1}{3}\)y - 2\(\frac{1}{3}\) | |
| -\(\frac{1}{4}\)y + 1\(\frac{1}{4}\) | |
| 7y - 8 | |
| \(\frac{2}{17}\)y + \(\frac{7}{17}\) |
